Fiber-optic internet isn’t just keeping up with the future—it’s paving the road for it. Built on strands of glass thinner than a human hair, it carries information at the speed of light. It’s the kind of technology that doesn’t just meet today’s needs, it anticipates tomorrow’s demands. Whether that’s ultra-realistic virtual reality, instant cloud computing, or the next wave of digital breakthroughs we haven’t even imagined yet.

Fiber is built on a technology that can handle massive increases in data demand for decades to come. This means it can deliver internet speeds far beyond what most households and businesses currently require, and upgrades can often be made without replacing the physical cables.

Another reason why fiber is future-proof is its ability to scale with minimal disruption. While other connection types may require significant hardware overhauls to improve speeds, fiber-optic networks can often achieve major performance boosts simply by upgrading the equipment on either end of the line. This scalability allows internet providers to adapt to new standards and higher speeds without digging up streets or replacing the core network. It’s a technology that grows with you, supporting everything from today’s HD video calls to tomorrow’s holographic conferencing and immersive experiences. This is the technology that provides you with the fastest internet speeds available.

Finally, fiber offers incredible reliability and durability. Fiber cables are immune to electromagnetic interference, less susceptible to weather damage, and can transmit data over longer distances without degradation. These qualities make fiber an ideal technology to support the ever-growing demands of smart homes, connected businesses, and emerging tech innovations. In short, some other internet technologies may eventually hit their limits, fiber has the performance headroom to carry us well into the future without missing a beat.

If you’ve looked into upgrading your home internet to a gigabit fiber connection, Frontier offers you different plans to fit your needs.

Fiber can get faster

Gigabit speeds are the current gold standard for home fiber optic broadband. Because Frontier fiber offers symmetrical upload and downloads speeds, you can enjoy speeds up to 7000 Mbps for both downloading and uploading with our 7-gig plan. That’s enough internet bandwidth for everyone in your house to stream 4K UHD videos, play any online games they want or work from home. All at the same time. But fiber internet cables are capable of supporting much faster speeds. Information is sent using lasers to transmit the data along thin strands of fiberglass at almost the speed of light.

Fiber is secure and reliable

With copper cables, data is sent as an electronic signal along the wires. With fiber optic cables, the data is sent as beams of light. This makes for a secure and reliable internet connection, especially over longer distances.

With fiber optic cable internet, data can be sent much farther with less attenuation—up to 60 miles in some cases. This is part of what enables fiber’s high speeds. It’s also what makes the fiber infrastructure so future-proof: Cables can be laid to new locations that were previously unviable.

Fiber is more durable

Fiber optic cables are resistant to weather conditions or whatever else Mother Nature can throw at them. The individual strands of fiberglass are wrapped in a protective cladding, then bundled together and wrapped in even more protective materials. It makes them waterproof, weatherproof and temperature-proof. Once a fiber cable is laid, it should last a long time without needing to be replaced.

As a bonus, unlike copper cables, fiber optic cables have limited scrap value—which means people are less likely to steal them.

Yes, Frontier Fiber is built for the future with gig speed

Our fiber has been designed for high-speed (up to a gig and getting faster), secure, reliable internet connections from the ground up. It’s meant to transfer large amounts of data long distances extremely quickly. Frontier Fiber connections aren’t going to be replaced by some new futuristic cable in the next few years—for fiber, the future is already here. Check here to see when it’s available at your address. So whether you want to move to a gig, 2 gig or the gig speed of the future, with Frontier you’ll be ready.
